Fergie's legFergieWe are a little confused by Fergie's leg in this snap.

We're not sure how it's got so wrinkly.

But this defo ain't the usual way it looks.

Fergie - of the Black Eyed Peas variety - went off trotting around Brentwood, LA, and was snapped not putting her best leg forward.

This is pretty unfortunate for her - we'd personally hate being snapped out pounding the tarmac and would sure look pretty hideous if we were.

But headphones on and drink in hand, nobody is holding this chica back.

Having a good ol' shufty at this photo we surmise that it's the jiggling of jogging motion that has made her bod react so.

Could it be that her skin just ain't as springy as it used to be?

This ain't no crime, it's just normal.

Shock, horror - a celeb showing signs of Joe Public behaviour.

But kudos to her for keeping fit and healthy, it's inspired us to do a bit of exercise ourselves in fact.
